Backers of the Robox 3D printer Kickstarter campaign "should have their printers in hand by the end of March," according to Robox CEO Chris Elsworthy.

Robox engineers have smoothed out all of the "foibles" in the plug and play printer and its accompanying software, and the machines are currently in production in China.

"We just wanted to make sure that when people press print, it does what people want it to do rather than having to spend hours fine tuning it," Elsworthy said.

In the meantime, engineers are working on additional heads to make the easy to use printer super versatile as well. The plan is to release a couple of new heads a year, with the first two coming before the end of 2014.

First on the design board is a "knife drag" head that would actually convert the printer into something of a CNC machine.

Users would be able to enter design files into the printer, which would then cut shapes out of paper to be glued onto DIY greeting cards popular in the United Kingdom right now.

The second head to be released this year would allow the printer's dual nozzle heads (a proprietary design company officials claim makes the printer up to 300 percent faster than similar machines) to print in two different materials simultaneously.

A print head that could make cake decorations out of frosting is also in the works for 2015.

The heads are secured with a single thumbwheel in the back and pop in and out easily.

The company raised £280,891 against a goal of £100,000 on Kickstarter last December, but Elsworthy does not foresee going that route again to raise money for the new designs.

Robox has received a small government grant to work on extruder designs and Elsworthy is hoping the revenue stream from printer sales will make up the difference.

"Hopefully it becomes self funding," Elsworthy said.
